Help a Bitch Out: He’s evil, maybe a pedophile.

Bitchery Reader Rachel sends this request for help:

My name’s Rachel and I’ve been reading your site for about a year now, and
I’m hoping that the bitchery can help me find one of the very first romance
novels I read. This was when I was 12 so it would have been 1995, though
the book could have been a bit older than that. Anyways, it was about a
little girl named Eleanor who grew up on an estate in Wales with one evil
(maybe pedophile) uncle and another (Uncle Evan) who was cursed with
gigantism. She had a plucky and noble governess named Charlotte who ended
up married to Uncle Evan, and Eleanor grew up and fell in love with a
servant named Owain who was a lot older than her. They got married and
split up for awhile and she became an actress and he went to America and
they ended up together HEA in Texas where he was a rich rancher (I think).

I remember a lot about this book because I wrote a book report on it which I
still have a copy of, but some how I never mentioned the name of the book or
the author in my report (and still got an A+!) and detailed google searches
of the character’s names has turned up nothing. There was also a rival
named Victor Thane, that I totally thought Eleanor should have picked over
Owain, so much so that I wrote an alternate last 5 chapters for extra credit
and so the book would end right. Do you think you could post this and help
me out?

A Welsh romance ending up on a ranch in America? With a possibly evil perhaps pedophile villain? Wow. This is like a full house of romance cliches – I’m so curious!
